90 Practical examples
Transient loading points (load cycle transient time / 60 min) refer to specification PDC0198
(revision G, chapter 7.3, page 12).
ABB Drives communication profile
The following sections show control sequence examples using the ABB Drives
communication profile. The Main Control Word (MCW) is the principal means of controlling
the converter from WTC. The Control Word is sent to the converter by the WTC. The
converter switches between its states according to the bit-coded instructions of the Control
Word. The Main Status Word (MSW) contains status information, sent to the WTC by the
converter.
